I too am having trouble with the Import contacts API. I am able to get all the way to an access token, but once there, when I try to use the given xoauth_yahoo_guid in the "http://social.yahooapis.com/v1/user/{0}/contacts" url, I get unauthorized errors. I have tried adding in the oauth tokens, both the ones from the request token and from the access token, but I still get an unauthorized error. Here is what my code looks like for building the url, and I use the basic OAuthBase class that was made for C#. Note, building it this way worked for every other step in the OAuth sequence. This is in a method that took an AccessToken class called token:

Kevin, did you find a solution to your problem? I am facing the same issue. Any help would be appreciated.

Thanks-Awais
